As shown in fig. 2-5, an embodiment of the present utility model provides a motor clamping tool, which includes a holding portion 1 and a clamping portion 2, wherein the holding portion 1 is a cylinder with two open ends, the clamping portion 2 is a ring body, the clamping portion 2 is disposed on one end face of the holding portion 1, and a plurality of locking structures are disposed on the clamping portion 2, and the locking structures are used for clamping and fixing mounting lugs 023, and the number and the position of the locking structures are adapted. Specifically, the locking structure includes a lock hole 21 and a sliding cavity 22, wherein the lock hole 21 is a blind hole with a downward concave upper surface of the clamping portion 2, the sliding cavity 22 is a groove with a concave inner sidewall of the clamping portion 2 toward an outer sidewall, the radian of the sliding cavity 22 is the same as that of the inner sidewall of the clamping portion 2, the sliding cavity 22 is communicated with the lock hole 21, and an included angle is formed between the length direction of the sliding cavity 22 and the axial direction of the lock hole 21, and the included angle is a right angle. The diameter of the inner ring 021 of the engaging portion 2 is equal to the outer diameter of the outer ring 022 of the bearing housing 02.

When the fixing assembly is used, the positions of the mounting lugs 023 and the lock holes 21 are aligned at first, the mounting lugs 023 and the lock holes 21 are close to each other, the outer ring 022 of the bearing seat 02 enters the inner ring of the clamping part 2, the mounting lugs 023 enter the lock holes 21, then the holding part 1 is rotated, the holding part 1 drives the clamping part 2 to rotate, the mounting lugs 023 enter the sliding cavity 22, and the mounting lugs 023 are extruded by the upper wall and the lower wall of the sliding cavity 22, so that the mounting lugs 023 are fixed in the sliding cavity 22. The holding part 1 adopting the barrel structure is convenient to hold on one hand, and the hollow structure of the barrel can leave an avoidance space for the bearing seat 02 on the other hand.

As can be seen from the above use, the height distance between the upper and lower walls of the sliding chamber 22 should be the same as the thickness of the mounting ears 023 to ensure that the mounting ears 023 are secured within the sliding chamber 22.

In some embodiments of the present application, a plurality of screw holes adapted in position are provided at the ends of the engaging portion 2 and the holding portion 1, so that the engaging portion 2 and the holding portion 1 are conveniently connected by bolts.

In this embodiment, the detachable connection between the engaging portion 2 and the holding portion 1 facilitates the replacement of different engaging portions 2, so that the present application can be applied to bearing seats 02 of different specifications.

The application also improves the structure of the sliding cavity 22 because the upper wall and the lower wall of the sliding cavity 22 are worn by different degrees after being used for many times, so that the mounting lug 023 cannot be fixed in the sliding cavity 22, and the upper wall and the lower wall of the sliding cavity 22 can be fully fixed and clamped on the mounting lug 023.

Taking the sliding cavity 22 as an example, when the mounting lug 023 enters the sliding cavity 22, the clamping part 2 rotates clockwise, and gradually extrudes with the stress surface 23 along with the rotation of the clamping part 2, so that the stress surface 23 clamps and fixes the mounting lug 023, and looseness of the planar sliding cavity 22 caused by friction is relieved.

Preferably, in both the counterclockwise and clockwise embodiments, the multi-stage folding line constituting the stress surface 23 is in a gradually convex state as a whole, and the multi-stage folding line includes diagonal lines and flat lines, wherein the flat lines are parallel to the upper wall of the sliding chamber 22, and diagonal lines are connected to both ends of either flat line. The oblique lines ensure that the whole multi-section folding lines are in a convex state, and the flat lines can ensure the contact stability of the mounting lugs 023 and the stress surface 23.
